Could the San Francisco 49ers look to the 2014 NFL Draft to find a backup for Kaepernick? It's a possibility according to NFL Draft analyst Matt Miller of BleacherReport.com.

"I think Tajh Boyd would be a good fit," Miller told 49ers.com this week.

Boyd, a succesful senior out of Clemson, completed 68.5 percent of his passes with 34 touchdown passes and 11 interceptions in 2013. Miller pointed to Boyd's skills matching up with how the 49ers use Kaepernick.

"He’s shown some running ability, has the downfield arm," said Miller before noting that Boyd, "needs to work on his mechanics especially on quick, underneath routes."

"He seems to have the physical attributes that fit with what the 49ers have done (at quarterback)," Miller noted.

Boyd's stock could rise significantly at the end of the week. Boyd will be one of the 300 college prospects attending the 2014 NFL Scouting Combine. There, the Clemson product has an opportunity to move up draft boards with a solid showing in field drills and interviews with various NFL teams.

Miller discussed the importance of the entire evaluation process. In the mind of the draft analyst, combine performances speak to a player's willingness to compete.

"I think the game film is most important, especially from an NFL team perspective," Miller said. "In the media, it hurts when a guy doesn’t throw because it’s one more thing to write about it. But I want to see a guy who is willing and able to compete against his peers. You want a guy who think he’s the best and has nothing to hide and is willing to show that on a big stage.

"If Andrew Luck can throw at the combine, one of the greatest draft prospects most of us have ever seen, then everyone should be able to throw there, too."

After sharing his thoughts on Boyd, Miller pointed out Northern Illinois quarterback Jordan Lynch and Connor Shaw from South Carolina as other athletic passers who could impress the 49ers later in the draft or as priority free agent signings.

Here are some of the other notable pre-combine thoughts shared by Miller:South Carolina DE Jadeveon Clowney

"He’ll be one of the most impressive players at the combine. I think it’s great that he’s already come and said he’s going to run the 40-yard dash and he’s going to do all of the workouts. I expect him to run in the high 4.4s and that’s incredible for a guy who is probably going to weigh 270-275 pounds. He’ll remind Niner fans a lot of Aldon Smith."

Combine Media Circus

"I think Johnny Manziel is the one everyone is going to want to talk to. There’s going to be a media firestorm to get access him. But’s always better for me when there are smaller tables for guys that not everybody is in love with. They don’t get the big podium, but I would love to talk to Davante Adams out of Fresno State, a redshirt sophomore. I’ll be finding out what he knows in terms of route tree, his football IQ, how was it playing with (quarterback) Derek Carr? How was that Fresno State able to help him acclimate to the next level?"

"I would look at cornerback as a big possibility. Bradley Roby from Ohio State stands out. He could be a fit there, a physical corner. Depending on what happens in free agency, (cornerback) could be a position they go. Marcus Roberson from Florida is another guy who seems to fit that mold... You want those tough, blue-collar football players and those guys fit that mold for sure."
